Donald Trump selected Mike Pence as his VP

The two will campaign together on Saturday

Washington (CNN)Democrats on Friday quickly seized on Donald Trump's selection of Mike Pence as his running mate, attacking him for his conservative record and promotion of traditional values. Republicans, however, widely praised the decision.

Hillary Clinton highlighted the social conservative's past statements on LGBT and abortion issues on social media.

"It's official: @realDonaldTrump just chose Mike Pence as his running mate. What you need to know about him," Clinton tweeted, attaching a video arguing that Pence was willing to harm Indiana's businesses and economy to discriminate against gay citizens and block abortion rights.

"It's no secret I'm a big fan of Mike Pence's. We're very good friends. I have very high regard for him. I hope that he picks a good, movement conservative (inaudible) and clearly, Mike is one of those," he said.

Sen. Tim Scott praised Pence's demeanor and said he will make the GOP "proud."

"I served with him for a couple of years. He's an articulate guy and has done a very good job," the South Carolina lawmaker said. "If he is the nominee I think we will be proud of what he represents."

Sen. Jeff Flake has frequently criticized Trump, but was more affirming of Pence.

"I'm a big fan of Mike Pence and I think he probably has a better chance of moving the candidate to where he maybe should be," the Arizona lawmaker said. "He's conservative and he's smart."

"Selecting Mike Pence as VP is just the latest admission that the Trump Agenda owes all its worst ideas to the House Republican Conference," she said in a statement. "There's not a dime's worth of difference between Donald Trump and the agenda Mike Pence fought for in the Congress -- the same hateful agenda his former colleagues continue to this day. "
